1. 如何安裝 Epel源到 RHEL/CentOS 7/6/5?
docker
RHEL/CentOS 7 rpm -ivh http://mirrors.ustc.edu.cn/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm RHEL/CentOS 6 ## RHEL/CentOS 6 # wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm # rpm -ivh epel-release-6.noarch.rpm 如何檢查epel是否安裝成功? 使用一下命令: # yum repolist [root@17-150 ~]# yum repolist 已加載插件:fastestmirror base | 3.6 kB 00:00:00 epel/x86_64/metalink | 5.6 kB 00:00:00 epel | 4.3 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/5): extras/7/x86_64/primary_db | 191 kB 00:00:00 (2/5): epel/x86_64/group_gz | 170 kB 00:00:00 (3/5): epel/x86_64/updateinfo | 807 kB 00:00:01 (4/5): updates/7/x86_64/primary_db | 7.8 MB 00:00:04 (5/5): epel/x86_64/primary_db | 4.7 MB 00:01:05 Determining fastest mirrors * base: centos.ustc.edu.cn * epel: mirrors.ustc.edu.cn * extras: mirrors.sohu.com * updates: mirrors.sohu.com 源標識 源名稱 狀態 base/7/x86_64 CentOS-7 - Base 9,363 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 11,769 extras/7/x86_64 CentOS-7 - Extras 449 updates/7/x86_64 CentOS-7 - Updates 2,146 repolist: 23,727
2. 安裝docker-ioshell
yum -y install docker-io yum install docker-engine
3. 啓動docker服務json
/etc/init.d/docker start
Starting cgconfig service: [ OK ]
Starting docker: [ OK ]
chkconfig docker on #設置docker服務開機啓動
4. docker命令補全
安裝docker自帶包:
缺乏下面的包,TAB會報錯centos
yum install -y bash-completion sh /usr/share/bash-completion/bash_completion 或者執行 source /usr/share/bash-completion/completions/docker
顯然,該腳本是用於bash自動補全的,可是,不幸的是,直接 source 執行該腳本後,docker命令後敲tab,有以下錯誤: bash
docker -bash: _get_comp_words_by_ref: command not found -bash: [: 1: unary operator expected -bash: [: 1: unary operator expected -bash: [: -eq: unary operator expected -bash: _get_comp_words_by_ref: command not found -bash: [: 1: unary operator expected -bash: [: 1: unary operator expected -bash: [: -eq: unary operator expected
難道docker的bash自動補全還能有問題? curl
解決辦法以下:
我這裏雖然安裝了bash-completion ,可是沒有執行其中的一個文件:
/usr/share/bash-completion/bash_completion
該文件中有上面缺乏的命令,執行該文件,從新開一個shell終端 就解決了。
5. 如何使用docker加速器
安裝/升級你的Docker客戶端
推薦安裝1.10.0以上版本的Docker客戶端。
您能夠經過阿里雲的鏡像倉庫下載:docker-engine、docker-ce
或執行如下命令:阿里雲
curl -sSL http://acs-public-mirror.oss-cn-hangzhou.aliyuncs.com/docker-engine/internet | sh -
針對Docker客戶端版本大於1.10的用戶url
您能夠經過修改daemon配置文件/etc/docker/daemon.json來使用加速器:spa
sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://sv1txjq6.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker
